GS-CO2-x-UN - Single Output Carbon Dioxide Sensors

A unique feature of this sensor is its ability to automatically detect what the controller input is set to, 4-20mA or 0-10Vdc. This removes the requirement for output jumpers that can be inadvertently set incorrectly. PCB LED indication of which output type is in operation is provided. Also available with a passive resistive output for temperature, along with other passive outputs.

PL-528 Static Pressure Transmitter

The PL-528 range of static pressure transmitters are suitable for use with a large range of liquids and gases compatible with the FPM (Viton) seal. The pressure transmitter is based on proven ceramic technology for exceptional performance speed and reliability.

GS-CO2-D Duct Mounted CO2 Temperature & RH Sensors 

Using a NDIR sensor for measuring CO2 concentrations and utilizing ABC (Automatic Baseline Correction) algorithm, they offer excellent long term stability & accuracy. Available with active temperature and RH outputs, as well as other passive outputs and user interfaces. A unique feature of this sensor automatically detects what the controller input is set to, 4-20mA or 0-10Vdc. This removes the requirement for output jumpers that can be inadvertently set incorrectly.

PA-6P-2 - Multi-Configurable Air DP Sensor

The PA-6P-x series have four field-selectable pressure ranges and selectable output signal type, which are easily defined by user selection switches. Making these ideal for measuring filter conditions, as well as many other applications in ventilation/air conditioning systems

PA-DPS Air DP Switches

These are highly sensitive air differential pressure switches, suitable for providing an indication of fan status and ‘dirty filter’ conditions. The switching setpoint is adjusted by means of a knob mounted under the main cover. Units are supplied complete with a duct fixing kit.
